Abstract

A baking sheet having a substantially flat silicone cooking surface, two rods extending along and coupled to opposite sides of the cooking surface, and two thermo-resistant handles coupled to and extending between the two rods. The thermo-resistant handles may be connected to the rods using thermo-resistant connectors. The connectors can disconnect from the rods and possibly be rotated to rotate the handles in positions adjacent to the rods to enable the baking sheet to be rolled into storage. The thermo-resistant characteristic of the handles enables users to lift the heated baking sheet without the use of oven mitts or other protective device.

Description

FIELD OF THE INVENTION

The present invention relates to a baking sheet and, more particularly, to a silicone baking sheet with removable thermo-resistant handles for easy handling and convenient storage.

BACKGROUND OF THE INVENTION

Baking sheets have long been widely and commonly used for supporting food products such as pre-baked food during the baking process. Patented designs include those disclosed in U.S. Pat. No. 6,279,771; and those in foreign Patents GB 2,154,860; EP 278055; DE 3832524.

Traditional baking sheets, however, pose handling problems after being exposed to high temperatures since they do not permit direct contact. In addition, with traditional baking sheets it is very difficult to place the sheet in an oven when it has cookie dough on it. In such case, the user generally must use a griddle or a metal tray. Many of the above references disclose enhanced baking sheets, for instance baking sheets adaptable to different widths, having an air pocket between the food product and the baking sheet, or eliminating the need for greasing the surface prior to baking. Nevertheless, there still is a need for a baking sheet enhanced to allow easy handling immediately following exposure to high temperatures as well as proper storage. There also is the need for a baking sheet that can be easily partially or completely removed from an oven for various purposes, such as to monitor baking status.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a baking sheet enhanced for easy handling before, during and after exposure to high temperatures.

It is a further object of the present invention to provide a self-supported baking sheet allowing for quick disassembly and easy storage.

In accordance with the present invention, a baking sheet includes a cooking surface, first and second rods coupled to the cooking surface, and first and second thermo-resistant handles coupled to the first and second rods.

As a feature of the invention, the first and second rods are coupled to opposite ends of the cooking surface, and each of the first and second thermo-resistant handles is coupled to respective ends of the first and second rods.

As another feature of the invention, the cooking surface is substantially flat and made of silicone. The cooking surface may also be a sheet of metal.

As a further feature of the invention, each rod is encircled by the silicone cooking surface at respective opposite ends of the silicone cooking surface.

As yet a further feature, the ends of the two rods are exposed and the handles are coupled to the exposed ends of the rods.

As yet another feature, the two rods are made of thermo-resistant material.

As yet an additional feature, connectors attach the handles to the rods. The connectors may be rotatable to allow the handles to be moved adjacent to the rods to allow easy storage. The connectors may be thermo-resistant. The connectors may also be detachable to allow complete disassembly of the components.

Various other objects, advantages and features of the present invention will become readily apparent to those of ordinary skill in the art, and the novel features will be particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF THE INVENTION

The present invention pertains to a novel baking sheet. As would be appreciated, the inventive baking sheet is intended for use by a layperson or a professional chef for the purpose of assisting in the baking of food products. Of course, the baking sheet may be utilized by other individuals for similar or different purposes.

Referring now to FIG. 1 of the drawings, the baking sheet 10 of the present invention includes a cooking surface 12 and a pair of

handles

14 a and 14 b. Cooking surface 12 preferably is flat and made of silicone. However, cooking surface 12 may be made of other material, such as from a suitable metal sheet, coated or uncoated, appropriate for cooking functions. Handles 14 a and 14 b may be made of metal, but preferably are made of thermo-resistant material, so as to allow direct handling immediately after exposure to extreme temperatures, for example, after baking. Handles 14 a and 14 b may be completely straight or be slightly curved to provide tensile strength to the silicone sheet. Handles 14 a and 14 b are attached to the shorter sides of cooking surface 12 utilizing four sets of

connectors

16 a, 16 b, 16 c and 16 d (an individual connector is sometimes referred to herein, for convenience, as connector 16).

Cooking surface

12 includes a pair of

rods

18 a and 18 b, disposed along the longer sides, as shown in the respective top and side view drawings of FIGS. 2 a and 2 b.

Rods

18 a and 18 b may be made of stainless steel or other appropriate material, but preferably are made of thermo-resistant material. In the preferred embodiment, cooking surface 12 is made of silicone and

rods

18 a and 18 b are encircled within the silicone (see FIG. 2 b ) along the two longer surfaces of cooking surface 12.

Rods

18 a and 18 b extend slightly beyond the encircled silicone and, as discussed further below, each connector 16 attaches a handle to an exposed end of a rod.

The structure of each connector 16 will be described with reference to FIGS. 3 a, 3 b and 3 c of the drawings. As shown in FIG. 3 a, each connector (16 a, 16 b, 16 c and 16 d shown in FIG. 1) is identified herein, for convenience, as a coupled element 20 (also called connector 20). Coupled element 20 is comprised of two components coupled to one another: connector component 22 and connector component 24 (or simply components 22 and 24). FIG. 3 a

shows components

22 and 24 coupled together.

Components

22 and 24 may be disassembled from one another as further discussed below.

FIG. 3 b shows component 22 alone and FIG. 3 c shows component 24 alone. As shown in FIG. 3 b, component 22 includes connection end 22 a and connection end 22 b. Connection end 22 a (also called rod/handle connection end 22 a) includes a round elongated inner core 22 a′ for receiving an end of one of the rods or an end of one of the handles. Connection end 22 b (also called socket end 22 b) includes a keyed, mostly round elongated inner core 22 b′ (with notch 23) and is designed to receive the counterpart connection end of the other connector component 24, discussed below. As shown, the apertures 22 a′ and 22 b′ within rod/handle connection end 22 a and socket end 22 b extend along longitudinal axes that are offset 90 degrees from one another.

Connector component

24 shown alone in FIG. 3 c includes

connection ends

24 a and 24 b. Connection end 24 a (also called rod/handle connection end 24 a) is similar to rod/handle connection end 22 a and includes a round elongated inner core 24 a′ for receiving an end of one of the rods or an end of one of the handles. Connection end 24 b (also called plug end 24 b) is in the form of a keyed plug (with projection 25) that is designed to be insertable into socket end 22 b. Plug end 24 b extends outwardly from rod connection end 24 a along an axis perpendicular the longitudinal axis of inner core 24 a′.

Connector components

22 and 24 are coupled together by inserting plug end 24 b of component 24 into socket end 22 b of component 22. Since socket end 22 b and plug end 24 b are “keyed” by means of notch 23 and projection 25, as shown, the components cannot be coupled together in an incorrect manner. That is, the components can only be coupled together to produce the coupled connector configuration shown in FIG. 3 a.

Baking sheet 10 of the present invention utilizes four of the connectors 20 shown in FIG. 3 a. As shown in FIG. 1, two connectors (16 b and 16 c) attach handle 14 a to

rods

18 a and 18 b, and two connectors (16 a and 16 d) attach handle 14 b to the other ends of

rods

18 a and 18 b. Referring to FIG. 4 a, connector 16 b (shown as

connector components

22 and 24 in FIG. 4 b) connects handle 14 a to one end of rod 18 a. As described above, connector 16 b contains two rod/handle connection ends (22 a and 24 a) and, in the preferred embodiment, rod/handle connection ends 22 a and 24 a are reversible, that is, each end can be coupled to an end of a handle and each end can be coupled to a disposed end of a rod. In this preferred embodiment, the dimensions of the ends of both

handles

14 a and 14 b and the ends of both

rods

18 a and 18 b are the same to provide for the versatility of allowing either end of each connector to be coupled to either a handle or a rod. Of course, in a non-preferred embodiment, it is contemplated that the ends of the handles and the rods are of different thicknesses (or other dimensions, as appropriate) and thus connection ends 22 a and 24 a are designed accordingly and thus may not be interchangeable.

The other three connectors 20 couple respective ends of handles to rods in a like manner as that described above. As would be appreciated, connectors generally are first connected to the handles with the orientations of the longitudinal axes of the exposed inner cores aligned in the same direction before coupling the connectors to the rods. In a preferred embodiment, the dimensions of the handles, rods and inners cores are appropriately sized to enable a user to be able to connect and disconnect the various connections with only a small amount of force. However, the connections should be relatively secure so as to prevent unintended disconnection. For example, gravity alone (i.e., holding the baking sheet in a slanted or vertical orientation) should not cause disconnection of the handles from the rods.

In the preferred embodiment, as further discussed below, a user of the baking sheet 10 of the present invention is able to disassemble the various components for further benefit discussed below. In a non-preferred embodiment, the baking sheet of the present invention is manufactured to produce connections between the handles, connectors and rods that cannot be disassembled by users of the baking sheet.

In accordance with the present invention, the handles can be partially disconnected or fully disconnected from the rods by users of the inventive baking sheet for various beneficial purposes. In particular, after use of the baking sheet 10, one end of each handle 14 a, 14 b may be disconnected from the respective rods to which they are attached and then the handles may be rotated 90 degrees to place them alongside the longer sides of cooking surface 12 (partial disconnection) (i.e., the axes along which the handles extend are parallel to the axes along which the rods extend). To facilitate such rotation, core 22 b′ of socket end 22 b of each connector (see FIG. 3 b) is internally keyed to allow such 90 degree rotation. Since the particular internal design of the connector components to facilitate rotation is well within the capability of one of ordinary skill in the art, further description thereof is not provided. Thereafter, baking sheet 10 may be easily rolled or pushed into storage, as needed. It is appreciated that either end of the two handles may be removed and rotated by users.

To fully disconnect the handles from the cooking surface 12, all of the

connectors

16 a, 16 b, 16 c and 16 d are removed from the rods to which they are connected. The connectors may then be removed from the attached handles. The connectors themselves may further be dissembled (see FIGS. 3 a, 3 b, 3 c). After disassembly, all of the components may be properly cleaned and stored for later use. Moreover, based upon the intended usage, benefits and preferences of users, multiple variations are possible. For example, various interconnections between the handles and the connectors, or the connectors themselves, may be made permanent during manufacture. That is, the baking sheet of the present invention may be manufactured to allow users to not be able to fully disassemble all of the components, as discussed above. For example, the connectors may be made to prevent their disassembly. For example, the rods and/or handles can be permanently secured to the connectors, e.g., via welding, permanent adhesive or other known technique. In yet another variation, connectors are not utilized, wherein the handles and rods are permanently secured together in any known manner.

As shown in the side view drawing of cooking surface 12 shown in FIG. 2 b,

rods

18 a and 18 b are positioned and embedded within the silicone forming cooking surface 12 to provide a cooking surface that has a completely flat lower surface to maximize the area of contact between the cooking surface and an oven grid or plate. In a non-preferred variation, the rods may be maintained below the cooking surface so that only the silicone surrounding the rods contact a flat surface such as a table top after cooking. Moreover, the rods may be coupled to the cooking surface in other manners, such as by co-injection, adhesively secured, welded or other appropriate method. In yet another variation, the baking sheet may be made solely of silicone with a silicone frame provided around the sheet.

FIG. 5 of the drawings shows a variation of the baking sheet in accordance with the present invention. Like the embodiment shown in FIGS. 1-4, the baking sheet in FIG. 5 includes a cooking surface 30, a pair of handles 32 (only one handle shown in FIG. 1), four connectors 34 (only two shown in FIG. 5) and a pair of rods 36. Each of these components has the same characteristics and features of the various components previously discussed, and may vary also as previously discussed. The embodiment shown in FIG. 5 differs, however, from the previously described embodiment in that each connector 34 is a single, unitary component with ends 34 a and 34 b for engagement with a respective end of a rod and a respective end of a handle. Each connector 34 provides for a fixed, that is, non-rotatable, engagement between a handle and rod. Each handle (with or without connectors 34) is removable from the cooking surface during use or storage of the baking sheet. Each handle 32 is curved as shown in FIG. 5 to maximize functionality and aesthetics. However, the curvature or shape of the handle may be different than that shown.

FIGS. 6 a, 6 b and 6 c of the drawings show another variation of the baking sheet of the present invention. The baking sheet shown is similar to the previously discussed variations. However, in this exemplary version, rods 42 disposed within cooking surface 40 include a bent at end 42 a (bent at about a 90 degree angle; other angles are possible) utilized for connection with handles 44. Each handle 44 includes an end 44 a made of rubber, plastic or other suitable material that receives bent end 42 a. As shown, bent ends 42 a are directed slightly upwards to enable easy connection to a handle. The handle and rods can be permanently secured to one another, for example, by welding. They also can be detachable. In the version shown, a stable handle construction is provided. In a variation, each handle can include a bent portion for connection to a non-bent end of a rod.

While the present invention has been particularly shown and described in conjunction with preferred embodiments thereof, it will be readily appreciated by those of ordinary skill in the art that various changes may be made without departing from the spirit and scope of the invention. For example, the handles may be attached along the longer surfaces of the baking sheet's cooking surface. As another example, the rods may be positioned along the sheet in a different manner, such as crossed, and additional rods can be utilized, for example, to provide further enhanced support to the baking sheet.

The various dimensions shown may be modified. For example, the baking sheet may have a square cooking surface or other shape. The baking sheet may also have a non-flat structure, and may include waves or other structural design, and/or other textures, on one side or both sides of the baking sheet. In particular, with a non-flat design, different patterns of air circulation are provided. Still further, connectors used to attach the handles to the rods may have designs quite distinct from that shown and described. Moreover, the shapes/cross-sections of the various components may be modified. For example, the handles may have square, rectangular, oval or other appropriate cross-section, with connectors adapted to receive such shaped handles/rods. The rods can be flat, rectangular, square, round, oval, triangular, hexagonal or other appropriate shape. In a further variation, the inventiveness of the baking sheet as discussed is applicable to a serving tray. In such case, the serving tray is similar in appearance to the cooking surface shown in the figures.

As mentioned above, the handles preferably are manufactured from thermo-resistant material. Each of the connectors may be made from any appropriately strong material suitable for cooking applications. The connectors likewise preferably are made from thermo-resistant material. Each of the rods may be made from stainless steel or appropriately strong thermo-resistant material. The handles and rods can be made from the same material, thus providing tension strength to both the frame and sheet. Given the particular design of the baking sheet of the present invention with the preferred thermo-resistant components mentioned, the baking sheet advantageously allows users to make contact with the baking sheet's handles shortly, if not immediately, after exposure of the baking sheet to various cooking temperatures. This advantageous feature in turn allows the removal from an oven or other heat source of the baking sheet using the handles and without the need for the use of oven mitts or other protective device.

The baking sheet of the present invention further provides for a design that enables a user to partially or fully remove the handles. Partially removing the handles, as discussed above, allows the baking sheet to be conveniently slid, moved or rolled into storage when needed. The handles and connectors may also be fully removed to allow for easy cleaning of the various components as well as easy storage. In particular, the baking tray can be stored in close proximity to other baking trays (even those not embodying the present invention) without wasting space needed for the handles. The handles can also be removed prior to baking and then be re-attached to the sheet while it is still in the oven to allow easy “cold-handle” removal of the sheet. The baking sheet therefore may be utilized without the handles and, if desired, handles can be attached to provide easy handling.

In addition, the flexibility of having removable connectors and handles allows for the easy replacement of such components as needed. Handles of various shapes, styles and sizes can be utilized based upon cooking styles, personal preferences and other desires of users. Multiple pairs of handles can be utilized with a single baking sheet, with the user selecting the particular pair of handles to be used based upon whatever factors the user considers. It is further possible to provide different sets of connection ends for the connectors for use with different shaped/sized handles.

Therefore, it is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
